Abstract
In the optical sheet according to an embodiment, at least one organic dye that selectively absorbs light in a specific wavelength band is added to a prism pattern layer, whereby it is possible to provide an optical sheet by a simpler manufacturing process than before, in which the color gamut is enhanced while a decrease in luminance due to light absorption is minimized. In addition, it is possible to secure optical and mechanical properties while preventing a degradation of organic dyes due to UV curing by adjusting the composition of the prism pattern layer.
